Abstract: METHOD AND DEVICE FOR TRAINING AN ADAPTIVE EQUALIZER BY MEANS OF AN UNKNOWN DATA SIGNAL     IN A TRANSMISSION SYSTEM USING DOUBLE SIDEBAND-QUADRATURE CARRIER MODULATION                      Abstract In the receiver of a system using double sideband-quadrature carrier (DSB-QC) modulation, the equalizer is trained by adjusting its tap gains so as to minimize the dispersion of order p,  , where E is the mathematical expectation, zn is the equalized signal, and R is a positive real constant.  To minimize the dispersion D(1), the tap gains are adjusted as a func-tion of the distance between the point Zn representative of Zn and a circle of radius R.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to the orientation of antennae on a satellite possessing at least one antenna comprising a horn rigidly connected to the body of the satellite, a movable reflector mounted on an orientable platform and at least one radio-frequency sensor in the horn using said antenna to control the orientation of said reflector.  The invention consists of: using a signal characterizing the pivoting of the orientable platform with respect to the body of the satellite to orient said satellite correctly with respect to the reflector in order to limit the pivoting of said platform; using the signals from at least one earth sensor in the same way as the signals from the radio-frequency sensor to control said reflector, so as to orient the beam towards the point sighted on the earth.  The invention is particularly useful for the control of the orientation of antennae, particularly on a satellite.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic rat killing device includes a box having an opening at its top and a stairway leading to its top.          A pair of closure plates are pivotally mounted at their one ends on the box for movement between horizontal positions where the two closure plates are mated together at their other ends to close the opening and vertical positions where the closure plates are separated apart to open the opening.   A solenoid is mounted on the box and has a stop lever normally engaged with the closure plates to hold them in their horizontal positions.   A container holding a viscous liquid is removably accommodated within the box.          A detector generates a detecting signal when a rat touches a bait.   The solenoid is energized to move the stop lever out of engagement with the closure member so that the closure plates are moved to their vertical positions, thereby causing the rat to fall into the viscous liquid.   A returning mechanism is operable to return the closure plates to their horizontal positions whereafter the stop lever is moved to engage the closure plates to retain them in their horizontal positions.

Abstract: DOCUMENT FEEDER WITH VACUUM SYSTEM HAVING     TWO CONTROL VALVES IN SERIES  ABSTRACT OF THE DISCLOSURE          A document feeder defines a sheet path along which a document sheet is fed across a platen of a copier/duplicator, for example, in order to copy the sheet.  An oscillating vacuum tube feeds sheets from a supply into the sheet path.  The feeder includes a platen vacuum transport having vacuum belts that move the sheet across the platen. The vacuum transport has a first vacuum plenum and a second vacuum plenum located along the sheet path. The first vacuum plenum has a relatively high level of vacuum to insure lifting of the sheet onto the vacuum belts.  The sheet is then transported into the area where it comes under the influence of the second vacuum plenum.  The second vacuum plenum has a somewhat lower level of vacuum, but it is sufficient to retain the sheet on the belts as the belts drive the sheet into engagement with a registration member.  One vacuum blower is used to establish a vacuum in the vacuum tube and in the two plenums.  Two control valves regulate the flow of air to the blower from the vacuum tube and one of the plenums.  One valve controls air flow to the blower from the vacuum tube and the second control valve.  The second control valve controls air flow from the first plenum to the first control valve.
